Don't discount 2 and 3 star hotels. Often they are rated that way because they have less facilities, but they have other things to offer. I love an older hotel for example, they frequently bagged the best spot on the beach or that corner in the Old Town. They can have larger rooms and higher ceilings. They may be family run and have five star service. Sometimes the best room in a 3 star hotel is the better option than the worst room in the 5 star hotel. I just feel a lot of people will automatically tick 4 and 5 on the booking engine and they might miss out on a great hotel.
